Service 03 // AI & machine learning

AI that does real work, safely.

We build assistants, document pipelines and agents that are grounded in your data, measured against real examples and wired into the systems your team already uses.

// 01 — What's included

From promising demo to dependable feature.

A demo takes a weekend; a feature people trust takes evaluation, guardrails and good engineering. We do both halves.

01

Use-case assessment

We test whether AI genuinely beats a simpler approach for your problem — and tell you plainly if it doesn't.

02

Retrieval over your data (RAG)

Search and Q&A across documents, wikis and databases with citations, access controls and freshness built in.

03

Agents & tool use

Models that call your APIs to look things up, draft, file or route work — with human approval where it matters.

04

Document processing

Extracting fields from invoices, contracts and forms into structured data, with confidence scores and review queues.

05

Evaluation & guardrails

Test sets built from real examples, automatic scoring, red-teaming and limits on what the system can see and do.

06

Classic machine learning

Forecasting, classification and computer vision models where they are a better fit than a language model.

// 02 — Deliverables

What you walk away with.

Not just a prototype: a measured, monitored system your team understands.

  • Use-case and feasibility report
  • Working prototype on your data
  • Evaluation set and quality scorecard
  • Production API or in-app feature
  • Prompt, model and retrieval configuration in code
  • Access controls and audit logging
  • Cost and latency monitoring
  • Model-risk and data-flow documentation
// 03 — Example use cases

Where it pays off.

Illustrative examples of AI that tends to pay for itself quickly when it's built carefully.

Use case 01

Ask-your-documents assistant

Staff ask questions in plain English and get answers drawn from policies, contracts or manuals — with links to the exact page.

Use case 02

Inbox and ticket triage

Incoming emails or tickets classified, summarised and routed, with suggested replies a person can approve in one click.

Use case 03

Invoice and form extraction

Supplier invoices or application forms read automatically into your finance or CRM system, flagging anything unusual.

Use case 04

Product search and recommendations

Semantic search that understands what customers mean, not just the words they type.

// 04 — Process

How an AI project runs.

01

Assess

Pick one high-value use case, gather real examples and define what 'good' looks like in measurable terms.

→ success criteria
02

Prototype

A working version on a sample of your data, scored against the evaluation set so progress is visible.

→ scored prototype
03

Harden

Guardrails, permissions, fallbacks, monitoring and cost controls; integration into your product or workflow.

→ production-ready
04

Operate

Track quality and cost in production, refresh evaluation sets and improve as models and data change.

→ measured in use
// 05 — Technology

// 06 — FAQ

Common questions.

Something not covered? Write to hello@spellegrinokey.co.uk.

Is our data used to train the AI models?

No. We use providers and settings where your data isn't used for training, keep documents in your own storage, and design access controls so the assistant only sees what the user asking is allowed to see.

How do you stop the AI making things up?

By grounding answers in retrieved sources, showing citations, refusing when the sources don't contain an answer, and measuring accuracy against an evaluation set before and after launch. No system is perfect, so we also design for human review where errors are costly.

Which model do you use?

Whichever performs best on your evaluation set for the right cost and latency. We keep the model choice behind a clean interface so it can be changed later.

How much does an AI project cost to run?

It depends on volume and model choice. We estimate running costs during the prototype, add caching and smaller models where quality allows, and put cost monitoring in place before launch.

Have a task AI could take off your plate?

Describe the workflow and the documents or data involved. We'll tell you honestly whether AI is the right tool — and what it would take.
